6 Operating modes
The selected operating mode is saved when the machine is switched off and activated when the machine is
restarted. Unauthorised button presses are indicated by three dashes (---) on the display (O on page EN
10).
The following four operating modes can be selected by pressing the “Mode” button (L on page EN
10):
6.1 TIG 4-cycle operation with HF
Indicator light N on page EN
10 illuminates
6.2 TIG 2-cycle operation with HF
Indicator light M on page EN
10 illuminates
for short weld seams and tack welding
6.3 TIG 2-cycle operation without HF (lift arc)
Indicator light K on page EN
10 illuminates
for short weld seams and tack welding. Touch the workpiece with the tungsten electrode.
6.4 Rod electrode welding
Indicator light J on page EN
10 illuminates
1st
cycle
Press the torch trigger. The shielding gas flows. After a brief initial
gas flow period (200 ms), the arc ignites with approx. 20% of the
set current.
2nd
cycle
Release the torch trigger. The current strength increases to the set
current level.
3rd
cycle
Press the torch trigger. The current strength reduces to the minimum
current level over the set slope-down time and remains at this level.
4th
cycle
Release the torch trigger. The arc goes out. The shielding gas
continues to flow for the set post-flow time.
1st
cycle
Press the torch trigger. The shielding gas flows. After a brief initial
gas flow period, the arc ignites with the set current strength.
2nd
cycle
Release the torch trigger. The current strength reduces to the
minimum level over the set slope-down time. At “Sd” = 0, the current
instantly drops to the minimum level. The arc goes out. The shielding
gas continues to flow for the set post-flow time.
1st
cycle
Press the torch trigger. The shielding gas flows. By removing the
tungsten electrode from the workpiece, the arc ignites with the set
current strength.
2nd
cycle
Release the torch trigger. The current strength reduces to the
minimum level over the set slope-down time. At “Sd” = 0, the current
instantly drops to the minimum level. The arc goes out. The shielding
gas continues to flow for the set post-flow time.
Welding with a hot start, i.e. with a current strength 20% above the set level.
Setting range: 5–140 A. The “anti-stick” function prevents the electrode from
sticking and burning out. The integrated “arc force” function makes it possible
to weld coarse-droplet electrodes by temporarily increasing the welding
current during short circuiting.
